Abstract

A powder dispensing assembly for an additive manufacturing machine is provided. The powder dispensing assembly includes a housing that defines a powder reservoir that receives additive powder; a first plate removably connectable to the housing, the first plate defining a first discharge orifice having a first discharge orifice geometry; and a second plate removably connectable to the housing, the second plate defining a second discharge orifice having a second discharge orifice geometry different than the first discharge orifice geometry, wherein with the first plate connected to the housing, the additive powder flows out of the first discharge orifice at a first dosing rate, and wherein with the second plate connected to the housing, the additive powder flows out of the second discharge orifice at a second dosing rate different than the first dosing rate.
